Note: Consider we need to find the circumference and area of the given circle.

Given:

A circle with radius 7.1 m.

To find:

The circumference and area of the given circle.

Solution:

Circumference of a circle is:

$C=2\pi r$

Putting
$r=7.1,\pi=3.14$ , we get

C=2(3.14)(7.1)

C=44.588

$C\approx 44.6$

Therefore, the circumference of the circle is 44.6 m.

The area of the circle is:

$A=\pi r^2$

Putting
$r=7.1,\pi=3.14$ , we get

A=3.14(7.1)^2

A=158.2874

$A\approx 158.3$

Therefore, the area of the circle is 158.3 sq. m.
